DC-DC Konvertör 12-35 volt

Good NiCd batteries are 2000 mAh and can be supplied with 5 A charging current in less than 1 / 2 hour load. On the green lawn flight is often the only car battery power source.For flight NiCd batteries with up to 7 cells (7 x 1.5 V, V = 10.5) is also good. With a higher number of cells is sufficient then the car battery voltage is not more. A Transverter, the car battery voltage to a higher stress level. A 20-cell battery for example, requires 30 V.
